Question
Please solve 2 and 4 correctly and clearly. Thank you
Show transcribed image text Calculate the standard heat of this isomerization reaction A gas stream (Stream 1) consisting of n-hexane in methane at 60 degree C and 1.2 atm is fed to a condenser. The dew point of the gas stream is 5 degree C considering hexane as the only condensable component. The gas is cooled to 55 degree C in the condenser, recovering pure hexane as a liquid (Stream 2). The effluent gas leaves the condenser saturated with hexane at 5degree C and 1 atm. Given this information, provide answers to parts a and b. Calculate the vapor pressure of n-hexane in mmHg at 5degreeC and 55degreeC using Antoine’s equation. Based upon the description of the process, fill in all missing information in the table below. Show all mass balances and any other necessary calculations clearly. Two thousand kilograms per hour of steam drives a turbine that delivers 75. kW of shaft work. superheated steam at 5 bar enters the turbine at 200 degreeC and the effluent stream is saturated steam at 1 atm. Assuming that potential and kinetic energy contributions to the overall energy balance are negligible, calculate the heat loss from the turbine in kW. A silicon wafer facility uses a mixture of water and sulfur hexafluoride as an etchant in their process. Water at 10degreeC (10. mol/min) is injected into a flow of liquid SF6 at 30degreeC and the combined stream, which contains 90. mol% water, is pre-heated to 90 degree C at 1 atm. Note that this process requires heating two streams to produce a combined stream at a higher temperature. Calculate enthalpies and completely fill in the missing information in the table given below. The specific heat of liquid SF6 is estimated to be 205 J/mol degree C. Calculate the rate of heat transfer required in kW.
